Answer:
The java program is as follows.
import java.lang.*;
public class Numbers
{
//variables to hold two numbers
static int num1=-8, num2=-2;
//method to return integer with higher magnitude
public static int maxMagnitude(int userVal1, int userVal2)
{
if(Math.abs(userVal1) > Math.abs(userVal2))
return userVal1;
else
return userVal2;
}
public static void main(String[] args) {
int max = maxMagnitude(num1, num2);
System.out.println("The number with higher magnitude among "+num1+ " and "+num2+ " is "+max);
}
}
OUTPUT
The number with higher magnitude among -8 and -2 is -8
Explanation:
1. Two integer variables are declared to hold the two numbers. The variables are declared at class level (outside main()) and declared static.
2. The variables are initialized with any random value.
3. The method, maxMagnitude(), takes the two integer parameters and returns the number with higher magnitude. Hence, return type of the method is int.
public static int maxMagnitude(int userVal1, int userVal2)
4. This method finds the number with higher magnitude using the Math.abs() method inside if-else statement.
if(Math.abs(userVal1) > Math.abs(userVal2))
return userVal1;
else
return userVal2;
5. Inside main(), the method, maxMagnitude(), is called. This method takes the two variables as input parameters.
6. The integer returned by the method, maxMagnitude() is assigned to a local integer variable, max, as shown.
int max = maxMagnitude(num1, num2);
7. The result is displayed to the user as shown.
System.out.println("The number with higher magnitude among "+num1+ " and "+num2+ " is "+max);
8. The class variables and the method, maxMagnitude(), are declared static so that they can be used and called inside main().
9. The variable, max, is called local variable since it can be used only within the main() where it is declared. It is not declared static.
10. The class is declared public since it has the main() method and execution begins with main().
11. The program is saved with the same name as the name of the public class having main(). In this case, the program is saved as Numbers.java.
12. No user input is taken for the two input parameter values. The static variables can be assigned any integer value and the program can be tested accordingly.
